Detailed Description

A base class describing a Mesquite::MeshDomain implemented on top of the TSTT geometry and classification interfaces.

A base class for Mesquite::MeshDomain implementations on top of the TSTT geometry and classification interfaces and static methods for constructing concrete implementations. The concrete implementations are not themselves in a header to avoid the need to include all TSTT headers if this header is included, for example indirectly through Mesquite_all_headers.hpp

GeomTSTT * create ( TSTTG::Geometry &  geom, TSTTM::Mesh &  mesh, TSTTR::Relate &  assoc, MsqError &  err  )

static

Create MeshDommain from TSTT classification and geometry interfaces.

Create an instance of an implementation of MeshDomain that uses the TSTTR/Lasso interface to get a handle for the geometric entity associated with a mesh entity and the TSTT geometry interface to evaluate the geometry.

Create a MeshDomain for a single geometric entity that uses the TSTT geometry interface for geometric evaluation.

Create a TSTT geometry MeshDomain for a single geometric entity. This implementation will be faster than the one that uses the classification interface because it assumes all entities in the mesh are in the interior of the single geometric entity specified. This implemenation in intended to be used only in the case where the mesh of a single surface is being smoothed and the mesh vertices on the boundary of the surface are fixed.
